Pub Package Build Status Code Coverage GitHub Issues GitHub Forks GitHub Stars GitHub License

A collection of extensively tested extensions that make Dart a better place:

Library Description
async Extensions to Stream.
cache Caching strategies and their expiry policy.
char_matcher Character classes, their composition, and operations on strings.
collection Extensions to Iterable and new collection types.
comparator Common comparators, and extensions to perform advanced operations.
diff Tools for comparing lists.
feature Information about the runtime environment.
functional Types and features known from functional programming.
graph Graph-theory objects and algorithms.
interval Continuous interval data type over a comparable type.
math Common mathematical functions.
number Number types: fraction, complex, quaternion.
printer Fluent interface to configure sophisticated formatter.
temporal Extensions to DateTime and Duration types.
tuple Tuple extension methods on generic records.

And there are more to come ...

This library is open source, stable and well tested. Development happens on GitHub. Feel free to report issues or create a pull-request there. General questions are best asked on StackOverflow.

The package is hosted on dart packages. Up-to-date class documentation is created with every release.

import 'package:more/tuple.dart';

Contributing

The goal of the library is to provide a loose collection of carefully curated utilities that are not provided by the Dart standard library. All features must be well tested. New features must have significant advantages over alternatives, such as code reduction, readability improvement, speed increase, memory reduction, or improved accuracy. In case of doubt, consider filing a feature request before filing a pull request.

History

This library started in April 2013 as I was working through the puzzles of Project Euler and encountered some missing features in Dart. Over time the code grew and became more useful in many other places, so I created this reusable library.

Some parts of this library are inspired by similar APIs in Google Guava (Google core libraries for Java) and Apache Commons (a repository of reusable Java components).
